Now, that I am at my #1 favorite feature, I am having a tough time deciding between these two - uniform initialization syntax or rvalue references, but I am going to have to go with initialization syntax this time.

Uniform initialization syntax, at first, doesn’t seem like a big deal, but it solves something that has irritated me personally forever in C++, initializing STL containers. So, this new feature accomplishes two things, makes all initialization syntax uniform with a new standardized brace notation and provides a clean mechanism for initializing STL containers. One other nice part of this feature is the capability to now initialize class member variables in the definition.

Regarding, STL containers, prior to C++11, a developer would need to load data into a container by iterating through the container and using push_back or other equivalent functions to insert data. But now, I just initialize a std::vector using the uniform brace syntax, such as:
